If you ask me, roasted potatoes are one of those side dishes everyone should know how to make.

These Irish roasted potatoes are simple, crispy on the outside, and fluffy on the inside. Russet potatoes get tossed with vegetable oil and a basic blend of salt, pepper, garlic powder, and paprika.

The trick is cutting them into even chunks so they roast at the same rate. A good vegetable oil with a high smoke point helps them get that golden, crispy exterior without burning.

They’re the kind of side dish that goes with just about anything—breakfast, lunch, or dinner. Perfect for a weeknight meal or weekend brunch.

Why You’ll Love These Irish Roasted Potatoes

Only 4 ingredients – You probably already have everything you need in your pantry right now – just potatoes, oil, salt, and pepper.
Crispy on the outside, fluffy on the inside – These potatoes get perfectly golden and crunchy while staying soft and tender in the middle, which is exactly what you want in a roasted potato.
Easy side dish – Just toss everything together and let the oven do the work while you focus on the rest of your meal.
Budget-friendly – Potatoes are one of the most affordable ingredients you can buy, making this a great option when you’re feeding a crowd without breaking the bank.

What Kind of Potatoes Should I Use?

Russet potatoes are the classic choice for roasted potatoes because they get that perfect crispy outside while staying fluffy on the inside. That said, you can definitely swap in Yukon Gold potatoes if that’s what you have on hand – they’ll give you a creamier texture and a slightly buttery flavor. Red potatoes work too, though they tend to hold their shape more and won’t get quite as fluffy in the center. Whatever you choose, just make sure your potatoes are firm and free of any green spots or excessive sprouting, which can make them taste bitter.

Options for Substitutions

This simple recipe is easy to customize based on what you have in your kitchen:

Russet potatoes: You can swap russets for Yukon golds, red potatoes, or even sweet potatoes. Keep in mind that Yukon golds and reds have a creamier texture and may cook a bit faster, so check them around the 35-minute mark.
Vegetable oil: Olive oil, avocado oil, or melted butter all work great here. Each will give you crispy potatoes with slightly different flavor notes – butter adds richness while olive oil brings a more savory taste.
Salt and pepper: Feel free to get creative with your seasonings. Add garlic powder, onion powder, paprika, or dried herbs like rosemary and thyme to mix things up. Just keep the salt and pepper as your base.

Watch Out for These Mistakes While Cooking

The biggest mistake people make with roasted potatoes is skipping the parboiling step, which is actually what creates that perfect crispy exterior – those roughed-up edges from shaking the drained potatoes give you way more surface area to crisp up in the oven.

Another common error is not preheating the oil in the pan before adding the potatoes, as cold oil leads to potatoes that stick and steam instead of getting that golden crust you’re after.

Don’t crowd the pan either, since overlapping potatoes will trap moisture and turn out soft rather than crispy – use a larger pan or two pans if needed to give each piece enough space.

Finally, resist the urge to flip them too often, as letting them sit undisturbed for those 15-minute intervals allows a proper crust to form before you turn them.

What to Serve With Irish Roasted Potatoes?

These crispy roasted potatoes are perfect alongside just about any protein you’re cooking up for dinner. I love serving them with roasted chicken, grilled steak, or even pan-fried pork chops – the crispy edges of the potatoes pair really well with any savory main dish. They’re also great for breakfast or brunch next to scrambled eggs and bacon, or you can turn them into a full meal by topping them with sour cream, chives, and shredded cheese. If you want to add some color to your plate, serve them with roasted vegetables like carrots, green beans, or Brussels sprouts.

Storage Instructions

Store: Keep your leftover roasted potatoes in an airtight container in the fridge for up to 4 days. They’re great to have on hand for quick breakfasts or side dishes throughout the week.

Freeze: These potatoes freeze pretty well for up to 2 months. Let them cool completely, then spread them on a baking sheet to freeze individually before transferring to a freezer bag. This way they won’t stick together in one big clump.

Reheat: The best way to bring back that crispy texture is to reheat them in the oven at 400°F for about 10-15 minutes. You can also use an air fryer for 5-7 minutes if you’re in a hurry. The microwave works in a pinch, but they won’t be as crispy.

Ingredients

8 russet potatoes (peeled and cut into 1-inch chunks for even roasting)
3 fl oz vegetable oil (I prefer Crisco for its high smoke point)
3/4 tsp salt
1/2 tsp pepper
1/2 tsp garlic powder
1/4 tsp paprika

Step 1: Prepare Potatoes and Preheat Oven

8 russet potatoes, peeled and cut into 1-inch chunks

Peel the russet potatoes and cut them into 1-inch chunks, keeping the pieces as uniform as possible for even cooking.

While prepping, preheat your oven to 400°F so it reaches temperature by the time you need it.

I like to cut my potatoes and place them directly into a bowl of cold water to prevent browning—this also helps rinse away excess starch, which helps them crisp up better.

Step 2: Par-Boil and Rough Up the Potatoes

Drain the potatoes from their water and place them in a pot of salted boiling water.

Cook for exactly 5 minutes—this softens the outside and starts the cooking process without making them mushy.

Drain thoroughly in a colander, then return them to the pot.

Shake the pot vigorously for 30 seconds to roughen up the edges; this creates crispy, textured surfaces that will turn golden and delicious when roasted.

Step 3: Heat Oil and Coat Potatoes

Pour the vegetable oil into a large roasting pan (about 9×13 inches) and place it in the preheated 400°F oven for 3-4 minutes until the oil is very hot and shimmering.

Carefully remove the pan and add the roughened potatoes, stirring immediately and continuously for about 1 minute to coat them thoroughly in the hot oil.

The oil should sizzle—this is what creates that crispy exterior we’re after.

Step 4: Season and Roast

3/4 tsp salt
1/2 tsp pepper
1/2 tsp garlic powder
1/4 tsp paprika

Combine the salt, pepper, garlic powder, and paprika in a small bowl.

Sprinkle this seasoning mixture evenly over the oiled potatoes and toss gently to distribute.

Return the pan to the 400°F oven and roast for 30-60 minutes, stirring and turning the potatoes every 15 minutes for even browning and crispiness.

The potatoes are done when they’re deep golden brown on most surfaces and tender when pierced with a fork.

Step 5: Serve

Transfer the golden roasted potatoes to a serving dish while they’re still hot and crispy.

I always serve these immediately because they’re at their absolute best when they have that contrast between the crispy exterior and creamy interior—waiting even 5 minutes will soften them slightly as they cool.
